Abstract: A method for washing laundry in a program-controlled domestic laundry-care appliance including the steps of heating washing liquid present in the tub and heating the washing liquid to a specific washing temperature set as a function of determined parameter values that are specific to the laundry being washed and/or the appliance.

Abstract: A method for determining a target rotational speed below an application rotational speed of a washing drum of a laundry treatment device having a drive and a vibrating system, wherein a dependence of a mechanical effect on items to be washed located in the washing drum on the respective nominal speed of the washing drum is used to ascertain the target rotational speed at which the mechanical effect is at the greatest. The mechanical effect at a respective target rotational speed is ascertained by measuring vibrating system movements of the vibrating system which exhibit greater frequency than the respective target rotational speed. The rotational speed at which the maximum vibrating system movement was measured is selected for carrying out the washing care procedure. The advantage of such a method is that the washing mechanics can be increased, thus improving the cleaning efficiency.

Abstract: A method for accelerating the wetting of washing in the variable-speed drum of a drum washing machine. A quantity of fresh water is introduced according to the determined quantity of laundry. The drum is driven at intervals and in a reversing manner in successive phases for a first determined length of time at an rpm which is adapted to the washing. The drum is stopped and/or driven at an rpm adapted to the wetting of the washing for a second pre-determined length of time, such that the water is especially effectively distributed over the washing by means of ladling devices located on the drum. The required quantity of washing liquid for the following washing phase is determined once the drum is driven at intervals and in a reversing manner at an rpm adapted to the washing after the second pre-determined length of time has come to an end.

Abstract: A method for washing shrinkable textiles in a program-controlled washing machine consisting in washing textiles in a rotatably mounted washing drum according to a process corresponding to textile requirements with a water flow and possibly washing agents, wherein a starting and operating time of a drum driving motor are predefined. A washing machine for carrying out said method is also disclosed. At the beginning of the washing process, the motor operates with a staring time rate which is greater than a possible staring time and which decreases step by step or continuously during the process in order to reduce a mechanical energy applied to the textile according to the shrinkability thereof which strongly increases along with the increase of the washing process time. In such a way, the textile is pre-wetted with an optimal water quantity or soapy solution without producing the excessive textile shrinkage.

Abstract: A drum shell having flow perforations in the rear zone thereof, for exchange of the washing liquid between the interior of the washing drum and the interior of a liquid tank, enclosing the above and, in the operating position for the washing machine, the lower shell line increasingly differs from a horizontal, on rising towards the front. Hollow, long lifting bodies, which are embodied to take liquid amounts from the deepest position thereof and raise the same, on rotation of the washing drum, to a raised position within the washing drum and to release the same from said raised position into the interior of the washing drum, inadequately wet the pieces of washing in the front region. According to the invention, the amount of water discharged in the interior can more effectively be applied to the laundry items, whereby the drum shell has a total surface of flow perforations.

Abstract: The sensor system of a water-bearing domestic appliance, in particular a washing machine comprising program control, supplies measured data, which can be evaluated for controlling the programs. Sensors are thus used to monitor the function of the mechanical drive of the domestic appliance. If a malfunction occurs in the drive system, e.g. if the V-belt for the washing drum splits, an alerting signal is triggered. According to the invention, the measured values of the sensor system taken when the drive unit is idle and in motion are evaluated in relation to one another and are optionally compared with a stored set value.

Abstract: A sensor system for a water-bearing domestic appliance for monitoring the treatment fluid in the appliance. The sensor system measures the treatment fluid parameters in a program sequence that includes alternating idle and in motion operations of the appliance. The measured treatment fluid parameters can be compared to known proper operational treatment fluid parameters.

Abstract: The washing process W does not immediately begin with a heating phase tIK-tOS at the beginning of a wash program with an untypically cold supply of water when a heating device is turned on, but rather once a delay phase D has elapsed. Said washing process ends after a post-wash phase without adding any heat energy once a defined constant time tEK-tOK has elapsed after the delay phase. The temperature of the water or lye at the end of or after the end of the period during which water is added F is determined. If the determined temperature is less than a standard value S for the amount of water which has freshly run into the lye container prior to the beginning of the washing process W, the heating device is turned on and the beginning of the washing process is postponed according to a defined duration of time D.
